Claims.

This invention relates to new and useful improvements in the flyers employed in connection with spinning machines.

One of its objects is to provide a fiyer of this 5 character which is so designed and constructed as to effect a balancing of the weight as well as the centrifugal force of the fiyer wire or wires, when in motion, and thereby produce an even, constant and. uniform tension of the threads during the spinning operation.

A further object of the invention is the provision of a balanced fiyer having simple and effective means for counter-balancing the weight of the fiyer wires, such means being so constructed as to be readily applied to and removed from the fiyer.

In the accompanying drawing:--

Figure 1 is a side elevation of a bobbin and spindle showing the improved fiyer operatively associated therewith. Figure 2 is an enlarged top plan view thereof. Figure 3 is a bottom plan view of the fiyer. Figure 4 is an enlarged cross section taken on line 4-4, Figure 2. Figure 5 is a detached perspective view of the balancing element of the fiyer. Figure 6 is a top plan of a modification thereof.

Similar characters of reference indicate corresponding parts throughout the several views.

Referring now to the drawing, Ill indicates a spindle of the usual tapered form and II a bobbin mounted thereon. The fiyer which is detachab'ly mounted on the bobbin spindle may be of any appropriate construction, that shown in the drawing consisting of an anchoring sleeve or journal l2 for attachment to the tapered end of the spindle, and a hub 13 rotatably mounted on the journal and carrying a wire base M to which the flyer wires [5 are suitably attached. By way of example, these fiyer wires project from one side of the hub and are retained in loops I6 formed in the base l4, a clamping ring I! being rotatably mounted on the hub and having substantially arcuate shaped gripping faces or segments I8 thereon for securely holding or clamping the wires against displacement relative to the retaining loops. As shown in Figures 1, 2, and 3, two fiyer wires are shown projecting from one side of the hub, one having a depending thread-engaging eye, which, during the rotation of the fiyer, assumes the outwardly deflected position seen by full lines in Figure 1. The inner ends of the fiyer wires are preferably bent out at an obtuse angle to be engaged by the clamping ring in the manner shown in Figure 2.

Projecting from that side of the fiyer-hub I3 diametrically opposite to that of the fiyer wires,- is an element for counter-balancing the weight and centrifugal force of the fiyer wires, when in motion, so that during the operation of the fiyer. an even and uniform tension of the threads is 5 constantly maintained. This counter-balancing element, by preference, is in the form of a wire member [9 which is substantially bail-shaped and which is so designed as to be readily applied to and removed from the wire base I4. To this end 10 the wire base has loops 20 thereon which are similar to the flyer wire-receiving loops I6, and the inner ends of the arms 2! of the bail-shaped element terminate in substantially hook-shaped portions each including an inwardly-facing 15 transverse portion 22 and an outwardly-facing attaching leg 23, as shown in Figure 5. The attaching legs are adapted for engagement with the companion loops 20 on the base-plate and the bail-portions 22 abut against the inner ends of 20 the loops in the manner shown in Figure 3, while the clamping ring l3 through its corresponding gripping segment I8 is adapted to engage the opposing sides of the bail-portions 22 to thereby effectually clamp the counter-balancing bail to 25 the base plate. In applying and removing the bail to and from the base plate, the clamping ring is turned to the position shown in Figure 3, whereby the bail is free to assume the position shown by dotted lines in said figure to permit its 30 ready removal from the base plate or to permit its legs 23 to be threaded into engagement with the loops 20.

By mounting the counter-balancing element IS in this manner, it can be readily applied to and 5 removed from the base plate, and they can be made in different weights of wire corresponding to the weights of wire used on corresponding flyer wires, so as to properly balance the fiyer. Furthermore, the clamping means which serves to 40 anchor the fiyer wires l5 in place also serves to detachably hold the counter-balancing element to the fiyer, thereby providing on the Whole a balanced fiyer which is manifestly simple and inexpensive in construction and which affords ready 45 renewal and replacement of both the fiyer wires and the balancing wire.

In the modified form of the balancing element shown in Figure 6, the bail 24 terminates in outwardly-bent hook-shaped portions or legs 25 5,0 with the shanks 26 in adjoining relation and adapted for disposition between the returning loops 20 of the fiyer base I4.

I claim as my invention:

1. A fiyer, comprising a body having a fiyer wire 55 projecting from one side thereof and an attaching loop in its opposite side, and an element for counter-balancing the weight of the flyer wire projecting from such opposite side of the body, said counter-balancing element being shaped from wire and having its inner end shaped. to provide an outwardly-facing attaching leg engaging said loop.

2. A fiyer, comprising a body having a fiyer wire projecting from one side thereof and a retaining loop in its opposite side, and a bail-like wire element for counter-balancing the weight of the flyer wire projecting from such opposite side of the body and having a substantially hook-shaped inner end including an outwardly-facing attaching leg detachably engaging said loop.

3. A fiyer, comprising a body having a fiyer wire projecting from one side thereof and a retaining loop in its opposite side, means on said body for clamping the fiyer wire thereto, and a bail-like wire element for counter-balancing the weight of the fiyer wire projecting from such opposite side of the body and having an attaching leg engaging said loop and a portion disposed for engagement with the fiyer wire clamping means, the latter holding the bail-like wire against displacement from its retaining loop.

4. A fiyer, comprising a body having retaining loops on its diametrically opposite sides, a fiyer wire projecting from one side of said body and engaging the companion retaining loop, a wire element projecting from the opposite side of said body to counter-balance the weight of the fiyer wire and having an outwardly-bent portion at its inner end to provide an attaching leg extending outwardly through the corresponding retaining loop, and a rotatable clamping ring arranged substantialy centrally of the body for interlocking engagement withsaid fiyer wire and said counterbalancing wire element.

5. The combination with a fiyer body having adjoining retaining loops thereon, of a wire baillike element detachably mounted thereon and having its side arms terminating at the inner end in substantially hook-shaped portions including outwardly-facing attaching legs adapted to engage said loops.
